Merge tag 'pidfd-fixes-v5.2-rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux

Pull pidfd fixes from Christian Brauner:
 "This fixes two bugs:

   - The first one reported by Linus whereby the pidfd-metadata binary
     was not placed in a .gitignore file.

   - The second one is rather urgent and fixes a locking issue found by
     syzkaller.

     What happened is that during process creation we need to check
     whether the cgroup we are in allows us to fork. To perform this
     check the cgroup needs to guard itself against threadgroup changes
     and takes a lock.

     Prior to CLONE_PIDFD the cleanup target "bad_fork_free_pid" would
     also need to release said lock. That's not true anymore since
     CLONE_PIDFD so this is fixed here.

     Syzkaller has tested the patch and was not able to reproduce the
     issue"

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
